NoClassDefFoundError使用Omnifaces :: Ajax :: update（）方法时出现异常

时间：2014-10-13 09:18:11

标签： ajax jsf omnifaces

当我尝试运行Omnifaces库的示例代码关于Ajax :: update（）方法时，我得到了NoClassDefFoundError异常;

我认为它关注客户端ID或组件ID，但我不知道如何避免此异常。

AjaxBean.java bean是以下

package com.tutorial;

import java.util.Arrays;
import java.util.Date;
import java.util.HashMap;
import java.util.Map;

import javax.faces.component.UIData;

import org.omnifaces.util.Ajax;

public class AjaxBean {

    public void update() {
        Ajax.update("form:timestamp");
    }

    public void callback() {
        Ajax.oncomplete("alert('Hi, I am the oncomplete callback script!')");
    }

    public void argument() {
        Ajax.data("foo", "bar");
        Ajax.data("first", "one", "second", "two");
        Map<String, Object> data = new HashMap<>();
        data.put("bool", true);
        data.put("number", 1.2F);
        data.put("date", new Date());
        data.put("array", new Integer[] { 1, 2, 3, 4, 5 });
        data.put("list", Arrays.asList("one", "two", "three"));
        Ajax.data(data);
        Ajax.oncomplete("showData()");
    }

}
